ADJUSTABLE SUPPORT FOR VVALL-RADIATORS.

Specification of Letters Patent.

Patented Aug. 14., 1917.

Application filed October 25, 1916. Serial No. 127,535.

b all whom it may concern.

Be it known that I, ALFRED S. Marrn'r'r, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have inventeda certain new and useful Improved AdjustableSupport for fall-Radiators, of which the following is a specification.

The present invention relates to an adjustable support for radiatorsections of the wall type and has for an object to provide a means tosupport an end of a radiator whereby expansion and contraction takeplace freely without placing strain or stress upon the radiator or itsassociated parts.

In wall radiators composed of a plurality of superposed sectionsarranged in the same plane, it has been found where the upper sectionsare supported at each end by a fixed nipple threaded into each sectionthat the relative variation in the length of the radiator sectionscauses the nipples to crack, break or be otherwise so distorted as tocause leakage and damage. By my present invention, I have overcome theforegoing defects through the elimination of afixed nipple support atone end and the provision of a removable adjustable member which may beinserted at any convenient point between the sections and adjusted tosupporting conditions without placing any limitation upon the freeexpansion or contraction of the radiator.

A further object of the invention is to provide an adjustable supporthaving suitable guide surfaces upon which the part supported by suchsurface or surfaces is free to move relatively thereto as conditions require.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown and described.

Referring to the drawings:

Figure 1 represents a side elevation of a wall radiator showing theadjustable support of my invention in operative position.

Fig. 2 represents a section on line 22 of Fig. 3.

Fig. 3 represents a plan of the support.

Fig. 4 represents a section in elevation of one of the saddle members.

Fig. 5 represents an elevation of the connecting nipple.

1 designates generally a separator and support for radiator sections ofthe type more particularly known as wall radiators wherein a pluralityof radiator sections are connected together and supported adjacent toand in substantially parallel relation to a wall. In radiators of thistype, it has been found, where one section is superposed upon another asillustrated in Fig. 1, that with supporting nipples at each end, thereis practically no allowance for the expansion and contraction of theradiator due to variations in temperature of the surrounding atmosphereor the medium within the section. As a result therefore of this naturaltendency of the metal to vary under temperature changes it has beenfound that the nipples break or crack causing leakage and its attendanttrouble. By my present invention, the construction of such radiators isnot only materially simplified but any section is free to expand orcontract without placing the connectors or supports under stress orstrain.

The adjustable support 1 consists, as illustrated by way of example, ofthree parts, an upper tubular saddle 2, a lower tubular saddle 8 and anintermediate control nipple 4:, which in assembled condition are adaptedto be positioned between an upper and a lower wall radiator section andsupport the former in such a manner as to permit free relative movementbetween the two sections. The upper saddle 2 is preferably provided witha screw threaded portion 5 adapted to receive the threaded end 6 of thenipple 4 and the lower saddle 3 is also provided with a threaded portion7 to receive the opposite threaded end 8 of the same nipple. It shouldbe noted that the ends of the nipple 4: are oppositely threaded, that isone is a right hand thread and the other a left hand thread so that asthe nipple 4 is turned in one direction or the other, the saddles Willbe simultaneously moved either toward or away from each other. Exceptfor this difference in the threading of the two saddles, theirconstruction is similar and hence the detailed description will belimited to one though the same reference numerals will be used with bothto indicate like parts. The saddles, as willbe understood, arepreferably of tubular construction and at the free end are transverselycut to provide a supporting surface 9 and a pair of alined seats 10, theformer having the general contour of the cooperating radiator face andthe latter being adapted to receive the rib 11 of the radiator section.The surfaces 9 in addition to forming a support have the function of aguide or way upon which the radiator element may move while expanding orcontracting. The seats 10 prevent lateral displacement of the adjustablesupport and therefore insure the parts being retained at all times inoperative position.

The control nipple a, in the preferred form, is pr vided with an openingor openings 12 for the insertion of a suitable implement, such as aspanner wrench or the like, whereby it maybe properly turned to causethe requir'edmovement of the two saddles. Thus in placing the device foruse, the saddles are normally sufliciently close together to permit thefree insertion of the support between the radiator sections, the lowersaddle seating upon the upper face of the lower radiator section whilethe seats 10 receive the rib 11. The nipple t is now rotated to causeseparation of the two saddles and consequently the upper saddle risesbeneath and into contact with the lower face of the upper radiatorsection while the seats 9 straddle the ribs 11 as an additional guardagainst the displacement of the device. It is preferable to tighten theadjustable members between the radiator sections just enough to maintainthe upper section correctly supported without shearing stress upon anyof the fixed nipples, though the degree of tightness may vary quitewidely without materially increasing the friction sufliciently toprevent the relative sliding movement due to expansion or contraction.

The device in effect is loosely positioned bet-ween the radiatorsections and in using the word loosely in the claims it is to beunderstood that it is employed with the meaning that the device is notfixed to either section other than by frictional contact.

It. will now be apparent that I have de vised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results it is to be understood that the sameis susceptible of modification in various particulars with out departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

lVhat I claim is:

1. In a device of the character stated, the combination of a radiatorsection fixedly supported at one end and an adjustable supportlooselyseating beneath the opposite end, said support having a guidesurface whereby said radiator section is free to move under expansion orcontraction.

2. In a device of the character stated, the combination of a radiatorcomposed of su perposed sections, the upper section of a pair ofsections being connected at one end to the lower section by a threadednipple connection and an adjustable support adapted to be looselyinserted between said sections at the free end whereby said uppersection is supported for free expansion and contraction.

3. In a device of the character stated, the combination of a radiatorcomposed of superposed sections the upper section of a pair of sectionsbeing connected at one end to the lower section by a nipple connectionand an adjustable support provided with upper and lower guide surfacesadapted to respectively sea-t loosely upon the lower face of the upperradiator section and the upper face of the lower section whereby freeexpansion and contraction cantake place between said sections.

4. In a device of the character stated, the combination of a radiatorcomposed of superposed sections, the upper section of a pair of sectionsbeing connected at one end to the lower section by a nipple, anadjustable support provided with upper and lower guide surfaces adaptedto respectively seat loosely upon the opposed faces of said radiatorsections and means to prevent lateral displacement of said adjustablesupport.

5; In a device of the character stated the combination of a radiatorcomposed of superposed sections, the upper section of a pair of sectionsbeing fixedly connected at one end to the lower section and anexpansible' support adapted to be loosely inserted be tween saidsections at the free end whereby unrestricted longitudinal expansion andcontraction can take place between said sec tions.

In testimony whereof, I- liave hereunto signed my name.
